PETER A. COUPAL, OF BOSTON, MASSACHUSETTS, AND CHARLES D. WOOD, OF LINCOLN, RHODE ISLAND, ASSIGNORS TO THE BOOT AND SHOE SOLE LAYING COMPANY, OF PORTLAND, MAINE.

SOLE-LAYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 335.016, dated January 26, 1886.

Application filed June 8, 1885. Serial No. 168,058.

To all whom it may concern.-

Be it known that we, PETER A. COUPAL, of Boston, in the county of Suffolk and State of Massachusetts, and CHARLES D. W001i,

of Lincoln, in the State of Rhode Island,

have invented certain new and useful Improvements in Sole-Laying Machines, of which the following is a specification.

This invention relates to that class of mam chines forpressing cement-coated soles against lasted bootor shoe uppers, in which the last holding the upper is rigidly supported and the cement-coated sole is pressed against thelasted upper by an elastic bed, which is movable to- 1 ward and from the rigidly supported last, and

is moved toward the last by mechanism controlled by the operator.

The invention consists in certainimprove ments in the construction of the sole-supporting bed and in the means employed for ad justing said bed toward and from the last, as we will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents 2 afront elevation ofanimproved machine. Fig. 2 represents a side elevation of the same. Fig. 3 represents a vertical section on line 00 m, Fig. 1. Fig. 4 represents a perspective view of a part of the machine.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents the last-supporting jack, which is composed of two standards, 23, one having a spindle at its lower 3 5 end adapted to be engaged with the spindlesocket in the heel portion of the last, and the other a toe-rest. Said standards are adapted to slide toward and from each other on the head, and have tapped sockets which receive 0 a right and left hand threaded screw-rod, b, journaled at its center in abearing in the head a, the rotation of said rod moving the standards 2 3 simultaneously toward and from each other and adapting them to different-sized lasts.

6 represents the supporting portion of the frame, from which rise two vertical. standards, f f, supporting the head 0.

9 represents the support for the cementcoated outer soles. Said support is composed (No model.)

ofa metallic block or holder, 4, having trunnions 5 5 projecting from its opposite sides, abed, 6, ofyielding rubber, supported by said block and having its central portion made thickest, as shown in Fig. 3, and two springsupported metal plates,7 7, under the thinner portions of the bed 6, the springs 8, supporting said plates,being applied to studs bearing against the plates, the springs being partially contained in sockets in said block. The truno0 nions 5 5 are journaled in sockets in a crosshead, i, which is adapted to slide vertically on the standardsff, and is operated by mechanism, hereinafter described. The block at is therefore adapted to oscillate so as to permit 6 the bed to adapt itself to the longitudinal inclination of the bottom of the last.

it represents a rock-shaft journaled inlugs ZZon the cross-head z, and provided with a lever or handle, m, and with short arms n n, projecting backwardly, the rock-shaft, arms, and lever being rigidly connected.

0 represents a treadle-lever pivoted at p to a fixed support, and having an arm 11.

q represents an arm or link pivoted at one end to the arm 19 and at the other end to the arm a. The arm 1) and link q constitute a toggle-joint, while said link and the arms 12 a constitute another toggle-joint.

- \Vhen the machine is to be operated, the le- 8c ver m is raised by the operator until the arms n n are brought approximately into line With the link q, thus partially raising the cross head i, block 4, and bed 6, and bringing the bed into the desired proximity to the bottom of the last. The parts are held in this position by the engagement of a spring-dog, 'r, on the lever m, with a segmental ratchet-bar, s, which is pivoted to the link q. The operator then places the cement-coated sole upon the 0 bed 6, and by depressing the treadle-lever throws the arm 19 and link q into alignment, or approximately so, and thus gives the bed an additional upward movement and presses the sole with the required firmness against the 5 lasted upper, the pressure being retained as long as desired by engaging the treadle-lever with a notched holding-standard, a. When the pressure has been sufficiently continued for the cement to set the operator disen- 10o I ver m, and arms n give the block 4 and bed 6 a greater extent of vertical movement than is afforded by the pressure devices consisting of the treadle-lever 0, its arm p, and the link q, thus enabling the bed to be sufficiently sepa rated from the bottom of the last to permit the easy removal of a boot or shoe therefrom after the attachment of each sole, while the ratchet-bar s and dog r enable the bed to be held at any desired height while the operator is applying the sole to the bed.

It is desirable that the bed be brought as close as possible to the bottom of the last before the sole is placed on it, and as the lastbottoms often vary in height the ratchet and dog enable the-bed to be supported at any desired height prior to the final pressing opera tion, the increased thickness of the rubber bed 6 midway between its ends enables it to conform to the curvature of the shank crosswise of the last more perfectly than it could if the rubber had been the same thickness at 1 the center as atthe ends, while the thinner to variations in the curvature of the last at the toe and heel. We do not limit ourselves, however, to the construction of the bed.

WVe do not claim anything shown in Patent No. 315,923, for sole-laying machine granted to A. Epple, Jr., April 14, 1885, but have improved upon the construction shown in said patent by the addition of the ratchet-bars and dog 9', and by the described peculiarities of the sole-support.

e claim 1. The combination, with the movable bed and its supporting devices, including the sliding cross-head, of the rock-shaft pivoted to M said cross-head and provided with the lever m and arms 11,, the link g, pivoted to the arms n,

the treadle-lever having an arm, 19, pivoted two subscribing witnesses, this 5th day of June, 1885.
